Embodiment
With reference to the accompanying drawings, describe the present invention in detail.
With regard to present portable terminal, have wireless clearing service (for example, Mobile business or k-merce) function, in order to realize this service, portable terminal is built-in with transmission of IRDA infrared data or short range RF radio frequency loop aerial.
The present invention is exactly the portable terminal that utilizes transmission of this IRDA of being built-in with infrared data or short range RF radio frequency loop aerial, is not the wireless mode by in the past, but by wireless clearing interface, communicating by letter between execution portable terminal and externally positioned type keyboard.
Fig. 1 is the embodiment that portable terminal and externally positioned type keyboard utilize IRDA infrared data transmission means to communicate as the 1st embodiment of the present invention.
In addition, Fig. 2 is the embodiment that portable terminal and externally positioned type keyboard utilize short range RF RF-wise to communicate as the 2nd embodiment of the present invention.
As shown in Figures 1 and 2, as with wireless mode to the required transmitter module of portable terminal (2) emission key data, externally positioned type keyboard (1) comprises IRDA infrared data transmission transmitter module (3) or RF radiofrequency emitting module (4).
As the acceptance division that receives with the key data of transmission of IRDA infrared data or short range RF RF-wise wireless transmission, portable terminal (2) comprises the transmission of IRDA infrared data (4) or short range RF radio-frequency antenna (not marking among the figure), and handles the key data that receives and also discern from the required processor portion (not marking the figure) of literal of keyboard input.
Processor portion is the part of control portable terminal molar behavior, for example MSM etc.
Behind the input characters, key data (when being infrared communication, is IRDA infrared data transmission (4) by the acceptance division that transmitter module (3,5) is moved terminal in externally positioned type keyboard (1); When being RF radio communication, be the RF radio-frequency antenna) receive.
After the key data that acceptance division receives was input to processor portion, the processing through set was shown on the display screen of portable terminal.
Below with reference to Fig. 3, the processing procedure of the wireless data that portable terminal receives is described.
At first, portable terminal judges whether this wireless data is key data after utilizing transmission of IRDA infrared data or RF RF-wise to receive wireless data.
If the wireless data that receives is the key data of keyboard emission, then discern keyboard; If not key data, then carry out other action.For example, when the wireless data that receives is the required wireless data of the service of settling accounts, then carry out settlement process in the past.
After processor portion has discerned keyboard, receive key data and handle by acceptance division, with the literal of identification keyboard input, the literal that is identified shows to the user by the display screen of portable terminal.
For the processing of the key data that receives from the externally positioned type keyboard,, get final product by adding in house software if the portable terminal of transmission of built-in IRDA infrared data or short range RF radio frequency loop aerial then need not change hardware.
In addition, for the hardware specification of transmission of the IRDA infrared data in the externally positioned type keyboard or short range RF radiofrequency emitting module and the communication software specification of use IRDA infrared data transmission or short range RF radio frequency loop aerial, owing to use original standard specification, be easy to realize.
Aforesaid utilization of the present invention can realize the portable terminal of wireless clearing service and have the externally positioned type keyboard of wireless transmitter module, when during input characters, having the user of increasing effect easily by the externally positioned type keyboard in portable terminal.
In addition, if can realize the portable terminal of wireless clearing service, then need not revise hardware, only by adding software, can easily use, therefore, the externally positioned type keyboard can be realized compatible with multiple portable terminal.
